Researchers have found new evidence that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation (AF), a common heart condition that causes an irregular and often abnormally fast heart rate. ...

Scientists at the University of Alabama at Birmingham have identified a molecular pathway that seems to contribute to the ability of malignant glioma cells in a brain tumor to spread and invade previously ...

(Medical Xpress)—If the heart following a heart attack is not sufficiently supplied with blood, heart tissue dies. In adult humans, the ability to heal itself is hardly developed. Scientists from the Max ...

Researchers at the Hebrew University of Jerusalem and in California have achieved a breakthrough in understanding how and why a promising anti-cancer therapy has failed to achieve hoped-for success in killing tumor cells. ...

(Medical Xpress)—In a new study published in the scientific journal Circulation, scientists at Karolinska Institutet and Karolinska University Hospital show that an enzyme called arginase might have a key ...

(Medical Xpress)—It seems as if a tumor deprived of oxygen would shrink. However, numerous studies have shown that tumor hypoxia, in which portions of the tumor have significantly low oxygen concentrations, ...

UCLA stem cell scientists have shown that two common tumor suppressor genes, TSC and PTEN, are vital to regulating the stem cell-like precursor cells that create the blood supply in Drosophila, the common fruit fly.

Since anti-cancer drugs are carried to tumors by the bloodstream, abnormal blood vessel development can hamper delivery. In a paper published Aug. 14 in Cancer Cell, researchers at Sanford-Burnham Medica ...

Scientists at the University of Liverpool have identified high levels of a number of genes in the naked mole-rat that may suggest why they live longer than other rodents and demonstrate resistance to age-related diseases.

Humans view the world through two eyes, but it is our brain that combines the images from each eye to form a single composite picture. If this function becomes damaged, impaired sight can be the result. Such ...

A new study published in Restorative Neurology and Neuroscience demonstrates that Chinese herbal medicine Ji-Sui-Kang (JSK), given systemically for three weeks after injury in rats, improved locomotor function, reduced tissue ...

Cancer cells break down sugars and produce the metabolic acid lactate at a much higher rate than normal cells. This phenomenon provides a telltale sign that cancer is present, via diagnostics such as PET scans, and possibly ...
